Problem statement

You are given a non-negative integer array nums. In one operation, you must:

  • Choose a positive integer x such that x is less than or equal to the smallest non-zero element in nums.
  • Subtract x from every positive element in nums.

Return the minimum number of operations to make every element in nums equal to 0.

Function

minimumOperations(nums: int[]) → int

Examples

Example 1

nums = [1,5,0,3,5]return = 3
In the first operation, choose x = 1. Now, nums = [0,4,0,2,4] In the second operation, choose x = 2. Now, nums = [0,2,0,0,2] In the third operation, choose x = 2. Now, nums = [0,0,0,0,0]

Example 2

nums = [0]return = 0
Each element in nums is already 0 so no operations are needed.

Constraints

  • 1 <= nums.length <= 100
  • 0 <= nums[i] <= 100
